COMBINED HARE/OW AND FLOAT OR CLOD CRUSHER.

Application filed April 7, 1924. Serialll'o. 704,657.

To all whomit may concern; 1 V I Be it known that we, PHILIP W. Simone, JoHN H. PURNELL, and IIIARRY I). CARR, citizens of the-United States, residingm; Hastings, county of Barry, State of Michigan, have invented certain new and useful Improvements in Combined Harrows and Floats or Clod Crushers, of which the fol lowing is a specification. V i Y This invention relates to improvements in combined harrows and floats or clod crushers." J

'llhemain objects of this invention are: First, to provide an improved implement ofthe class described which is very efficient,

L the ground being thoroughly covered for crushing the clods and smoothing and also thoroughly harrowed.

Second, to. provide aniinproved implement having these advantages which is quite simple in structure and at the r the parts are so arranged that they are not likely to be injured in use.

Third, to provide an implement of the class described which is easily adjusted to support the teeth, in the desired relation to the surface worked, that is, to control the depth which theteeth shall enter the ground. 7

Fourth, to provide in an implement of the class described improved means of'mounting the teeth whereby they may be effectively supported in stepped relation and the teeth positioned relative to each other to compensate for listortion or lateral springing thereof. j T

Objects pertaining to details and econo hues of construction and operation will definitely appear from the detailed descrip tion to follow. 7 We accomplish the objects of our inven tion by the devices andmeans described in the following specification. The invention is clearly defined and pointed out in the claims;

A structure ment of our invention is clearly illustrated in the accompany' ing drawing forming a part of' this application, in which Fig. I is a plan view of a structure embodying the features of'our invention, a portion of the teeth being'omitted and others partially broken away for convenience in illustration.

Inthe drawing, similar reference charactersrefer to similar parts throughoutthe several views, and the sectional views are taken lookinginthe direction of the little arrows at the ends of the section lines.

Referring to thedrawing, we provide a pair of float members 1 of substantial width,

these float members being disposed in a rearwardly diverging relation and inclined inwardly as i lustrated. At their front ends the float members are connected to a triangular shoe 2, the shoe being upwardly offset at 3 to receive the forward ends of the float members. e y i The shoe terminates at its forward end in "an upwardly projecting draft standard at having a series of holes 5 therein withwhich the draft clevis 6 may be engaged.

Each float member is provided with a pair of uprights 7 which are supported in the sockets 8 carried-by the floats. uprights are connected by the cross bar 5) having a downward offset 10 therein as shown in Fig. IV. The rear uprights are connected by thecross bar 11 connected to the uprights by means of theyoke-like couplings 12, the couplings carrying the, bractets or braces 13 to facilitate connecting the cross bars thereto; see Fig. III.

v The longitudinal bars 14 are secured to these cross bars and in addition to constituting frame members form a supportfor the seat 15 carried by the spring standard 16-. Draw bars 18 extend rearwardly from the draft standard 4 and are connected to the frontends of these longitudinal bars 1% and This arrangement of parts results in a rigid frame and The front 1 ti a til?) (:11. which is adapted to withstand the strains to which it may be subjected in use.

fi e provide a pair of tooth bars which are mounted on the hangers it having laterally projecting spaced cars 22 :ilidaliil engagin the uprights T. The teeth in the structure illustrated are spring teeth, the same being mounted on the brackets 24rprojecting inwardly from the tooth bars. 'lhesc brackets have tlat heads or plates at their outer ends havii'ig holes Qt; therein and slots The holes at} are engaged by bolts 52% while the slots are engaged by bolts :iti so that. the braeluts may be augularly adjusted relative to the tooth bars, thereby positiouiiug' the teeth. It will be uuderatiiiod that sprin teeth are sometimes ilistorted in use and it is to he desired that they shall be uuitm'uily spaced, particularly where provided with plates as in the structure illustrated.

The tooth bar hangers are adjustahly supported upon the uprights by means ot the bars ill) which are arranged between the ears of the hangers and are arried by the links 31 and 3d, the bars being slid-able through the hangers. The rear links :32 are extended into adjusting levers Ill}. The adjustin; 'acl-zs 3st are pivotally mounted on the bars 30 at 35 to engage the pin-like keepers Sit on the rear tooth bar bangers. lland levers 3? are pivotei. at- 38 on the adjusting levers and c nnected by the links to the racks 34-. By this means the ra may be tilted to engage them from the keeper pins, the racks engaging- Willi the pins by gravity. T his provides a very simple and at the same time a substantial means ot securing the parts in their ad usted position.

The pivots 35 ot the racks iii are pro vided with spacing sleeves it) to prevent clamping oi the racks. The pivots ail, eonnet-ting the hanger bars 330 to the support- Lin links are provided with spacing sleeves lit, these spacing sleeves also sorting as bushings to receive the wear oi the parts, the saine being illustrated. as oi? bearing metal.

"the teeth 23 are adjustably secured to the tooth supporting brackets 2i by means of the clips 4:3 and the bolts a l, the springs terminating, in the curved ends it) engaging the ln'acket's as shown in Fig. IX.

The uprights T are preferably oi rectangular cross ection and the openings 22 in the arms .22 ot the brackets '21 are elongated as shown in Fig. X so that the parts do not bind should the float members he sprung as might occur when resting upon a stone or other obstruction.

"the tloat members or clod erushers not only smooth the ground but crush the ciods and lumps so that the ground is left in a very desirable condition.

We have illustrated and described our improvements in an emboiiliment which we have 'lound very priwtical. li e have not attemptedto illustrate or describe certain modifications or ada itations as we believe the disclosure made will enable those skilled in the art to which our invention relates to embody or adapt the same as may be desired.

liaviug; thus described our invention what we claim as new and desire to secure by Letters Patent is:
